Question
is it easy to replace rear shocks? rear wheels need to come off? i have drive way
do i need to jack it up? can you give me step by step replacement process
thank you . 1998 sienna

Answer
Yes , it needs to be off the ground to relieve the pressure on the shocks,it's easier if the wheels are off,the differential housing needs to be supported with another jack because it will drop down when the shaocks are removed so there needs to be a way to raise it back up to reinstall the new shocks.
